SAFETY NOTICE
Many electrical and mechanical parts in DMD™
Projector have special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be
necessarily increased by using replacement components
rated for higher voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical

TEST PROBE
components having such features are identified by “å”
and shaded areas in the Replacement Parts Lists and
Schematic Diagrams. For continued protection,
replacement parts must be identical to those used in the
original circuit. The use of a substitute replacement parts
which do not have the same safety characteristics as the
factory recommended replacement parts shown in this
service manual, may create shock, fire or other hazards.
CAUTION: FOR CONTINUED PROTECTION
AGAINST A RISK OF FIRE REPLACE ONLY WITH
SAME TYPE F701 (6.3A, 250V)
»Use an AC voltmeter having with 5000 ohm per volt,
or higher, sensitivity or measure the AC voltage drop
across the resistor.
»Connect the resistor connection to all exposed metal
parts having a return to the chassis (antenna, metal
cabinet, screw heads, knobs and control shafts,
escutcheon, etc.) and measure the AC voltage drop
across the resistor.
All checks must be repeated with the AC cord plug
connection reversed. (If necessary, a nonpolarized
adaptor plug must be used only for the purpose of
completing these checks.)
Any reading of 0.75 V peak (this corresponds to 0.5
mA peak AC.) or more is excessive and indicates a
potential shock hazard which must be corrected before
returning the monitor to the owner.
BEFORE RETURNING THE PROJECTOR:
(Fire & Shock Hazard)
Before returning the receiver to the user, perform the
following safety checks:
1. Inspect all lead dress to make certain that leads are
not pinched, and check that hardware is not lodged
between the chassis and other metal parts in the
projector.
2. Inspect all protective devices such as non-metallic
control knobs, insulation materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacitor networks, mechanical
insulators, etc.
3. To be sure that no shock hazard exists, check for
leakage current in the following manner.
»Plug the AC cord directly into a 120 volt AC outlet. (For
North America)
»Plug the AC cord directly into a 110 ~ 240 volt AC outlet,
and connect the DC power cable into the projector's DC
jack. (Do not use an isolasion transformer for this test).
(For Others)
»Using two clip leads, connect a 1.5k ohm, 10 watt
resistor paralleled by a 0.15µF capacitor in series with
all exposed metal cabinet parts and a known earth
ground, such as electrical conduit or electrical ground
connected to an earth ground.

Comme de petites quantités de radiation UV sont
émises par une ouverture entre les ventilateurs as-
pirants, il est recommandé de placer le capuchon de
l’optique optionnelle sur l’ouverture pendant l’entretien
pour éviter une exposition des yeux et la peau.
Since small amounts of UV-radiation are emitted
from an opening between the exhaust fans, it is rec-
ommended to place the cap of the optional lens on
the opening during servicing to avoid eye and skin
exposure.
DANGER ! –– Never turn the power on without the
lamp to avoid electric-shock or damage of the devices
since the stabilizer generates high voltages at its start.
UV-RADIATION PRECAUTION (Continued)
Lamp Replacement
Note:
Since the lamp reaches a very high temperature during
units operation replacement of the lamp should be
done at least one hour after the power has been turned
off. (to allow the lamp to cool off.)
Installing the new lamp, make sure not to touch the
lamp (bulb) replace the lamp by holding its reflector
2.
[Use original replacement only.]
DANGER ! –– Ne jamais mettre sous tension sans la
lampe pour éviter un choc électrique ou des
dommages des appareils car le stabilisateur génère
de hautes tensions à sa mise en route.

Precautions for using lead-free solder
1Employing lead-free solder
"PWBs" of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the
PWBs and service manuals. The alphabetical character following LF shows the type of lead-free solder.
Example:
2Using lead-free wire solder
When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional
lead wire solder may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40°C, we recommend you
to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit,
contact our service station or service branch in your area.
3Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is about 220°C which is higher than the conventional lead solder
by 40°C, and as it has poor solder wettability, you may be apt to keep the soldering bit in contact with the PWB for
extended period of time. However, since the land may be peeled off or the maximum heat-resistance temperature of
parts may be exceeded, remove the bit from the PWB as soon as you confirm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on
and off the power of the bit as required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after
every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
Be careful when replacing parts with polarity indication on the PWB silk.

RESETTING THE TOTAL LAMP TIMER
●Resetting the total lamp timer
When replacing the lamp, reset the total lamp timer in the procedure below.
■The warning lights (power indicator, lamp indicator and temperature warning indicator) on the projector indicate
problems inside the projector.
■If a problem occurs, either the temperature warning indicator or the lamp indicator will illuminate red, and the
projector will enter standby mode. After the projector has entered standby mode, follow the procedures given
below.
Lamp
■It is recommended that the lamp (sold separately) be replaced when the remaining lamp life becomes 5% or less,
or when you notice a significant deterioration in the picture and color quality. The lamp life (percentage) can be
checked with the on-screen display.
■Purchase a replacement lamp of type AN-100LP from your place of purchase, nearest Sharp Authorized Projector
Dealer or Service Center.
About the lamp indicator
When the remaining lamp life becomes 5% or less, (yellow) and "Change The Lamp" will be
displayed on the screen. When the percentage becomes 0%, it will change to (red), the lamp will
automatically turn off and then the projector will automatically enter standby mode. At this time, the
lamp indicator will illuminate in red.
If you try to turn on the projector a fourth time without replacing the lamp, the projector will
not turn on.
About the temperature warning indicator
If the temperature inside the projector increases, due to blockage of the air vents, or the setting location,
"" will illuminate in the lower left cor ner of the picture. If the temperature keeps on rising, the lamp
will turn off and the temperature warning indicator will blink, the cooling fan will run, and then the projec-
tor will enter standby mode. After " " appears, be sure to perform the measures described on page
53.

•If the temperature warning indicator illuminates, and the projector enters standby mode, follow the
possible solutions above and then wait until the projector has cooled down completely before plug-
ging in the power cord and turning the power back on. (At least 10 minutes.)
•If the power is turned off for a brief moment due to power outage or some other cause while using
the projector, and the power supply recovers immediately after that, the lamp indicator will illumi-
nate in red and the lamp may not be lit. In this case, unplug the power cord from the AC outlet,
replace the power cord in the AC outlet and then turn the power on again.
•The cooling fan keeps the internal temperature of the projector constant and this function is con-
trolled automatically. The sound of the cooling fan may change during operation because the fan
speed may change and this is not a malfunction.
•Do not unplug the power cord after the projector has entered standby mode and while the cooling
fan is running. The cooling fan runs for about 90 seconds.
